Research Profile

In past research, Stoye explored connections between statistical decision theory and applied economic analysis, with special attention to treatment/policy choice problems and to minimax regret as optimality criterion. In axiomatic analyses, he provided normative foundations for minimax regret and related criteria [1,2,3]. Parallel work in econometrics undertook finite sample (non-approximate) analysis of econometric treatment choice problems, e.g. the use of covariates in treatment assignment [4,5,6]. Stoye also advanced the literature on partial (set valued) identifiability of parameters and on inference in such settings [7,8]. More recently (with Stefan Hoderlein, Boston College), he proposed statistical tests of revealed preference analysis from microeconomic theory, asking whether the homo oeconomicus model is testable under otherwise weak assumptions on real-world data [9,10].

Some of Stoye’s current research extends this last project. With Yuichi Kitamura (Yale), he identifies the precise empirical content of Random Utility models in repeated cross-section data, assuming unrestricted unobservable heterogeneity among consumers and therefore an infinite dimensional nuisance parameter. Their statistical test overcomes both computational and theoretical (in the form of nonstandard asymptotic behavior) hurdles. It is extended to other, less standard economics models in work with Kitamura, Rahul Deb (Toronto), and John Quah (Johns Hopkins).The long-term vision is to fundamentally rethink the large economics literature on nonparametric demand, complementing its current “specific to general” approach (i.e., imposing an extremely tight structure and maybe gradually relaxing it) with a “general to specific” approach that initially tests whether data are consistent with minimal economic assumptions and, in future research, gradually relaxes the generality to obtain tighter conclusions. In other early stage research, Stoye (with Hiroaki Kaido, Boston University, and Francesca Molinari, Cornell) develops confidence sets for the optimal values of programs with estimated objective function as well as constraints. These sets will be valid uniformly over a large class of sampling processes and without so-called constraint qualifications. Notable applications are to policy counterfactuals in economic models as well as to projections of partially identified parameter vectors and are being explored empirically.
